摘要
CoupModel模拟范围广泛,几乎涉及了陆面过程的各种环节,且具有动态预测性。该模型不但能够较为准确地模拟森林、农田、湿地以及冻土等多种生态系统的土壤水热运移和碳氮循环等过程,还能够科学地预测气候变化背景下的增温潜势。通过对CoupModel的耦合原理及特点、数据的输入输出、多种参数估计方法及模拟结果检验等方面的详细介绍,深入了解了利用该模型模拟土壤-植被-大气系统的物质能量过程;CoupModel在国外多个国家和地区获得应用与认可,引入我国后,通过更改部分参数也在多个地区得到验证。在综合众多前人研究成果的基础上,将该模型与几种使用较广泛的同类模型进行了简单的对比分析,随后从模型参数简化、适用性验证和模型尺度等方面对其未来研究进展进行了探讨。
CoupModel simulation covers a wide range of aspects of land surface processes and has the characteristic of dynamic predictability.The model can not only accurately simulate the processes of soil water and heat transfer and carbon and nitrogen cycle in forest,farmland,wetland and permafrost ecosystems,but also scientifically predict the potential of temperature increase in the context of climate change.CoupModel is used to simulate the mass and energy processes of the soil-vegetation-atmosphere system in detail through its coupling principle and characteristics,data input and output,various parameter estimation methods and simulation results verification.etc.CoupModel has been applied and approved in many foreign countries and regions,and the introduction to China has also been verified in many regions by changing some parameters.Based on the many previous research results,we compared CoupModel with other widely-used models with similar functions.The future research progress should be discussed from the aspects of simplification of model parameters,validation of applicability and model scale.
